[How-to] Guide to Rooting with software version LS670ZVC

[coadman]

My phone is not rooted, but I may want to do so in the future. Is there anything I can do, to keep that option open(with the update looming?) thanks

If you wish to root with the VC update, use the LG tool to update. That can be found here.

If you have already installed the OTA update (didn't use the LG tool), read the original post for further instructions.

1) place a & c in the same directory--does this mean in the same folder? I am not familiar with how to place items in a specific "directory"...

2) run KP500-Utils-EN.exe from a windows command prompt--what is the command for this and why can one not just run the application from where ever it is stored?

3) choose option J - Flash with assistant (file .cab)--after opening the application I get the err msg, Error during the loading DLL. What does this mean? Im sure it has something to do with the directory, to the answer to the first question will likely solve, yes?

I'd like to get back to V9 so I may root, but this is my first go around with an android and I'm not on the same page with terminoligy.

You need to run the v8 to v9 update.zip to mount /system

 

[lionedas]

Yup that's one step I left out thinking since I came from v9......

Thanks

I must be doing something wrong...

The KP500 Util opens the LG Phone Updater and after only a few minutes I receive this error:

I made some clarifications to the instructions to address the questions you brought up.

1) place a & c in the same directory--does this mean in the same folder? I am not familiar with how to place items in a specific "directory"...

Yes, folder and directory are the same. For example you may have placed everything in C:\KP500-Utils-EN-v0.4.2.

2) run KP500-Utils-EN.exe from a windows command prompt--what is the command for this and why can one not just run the application from where ever it is stored?

You would open a command prompt (start menu->run - cmd.exe)
Then change the current folder/directory to the one you placed your files (C:[enter] cd KP500-Utils-EN-v0.4.2[enter])
Then run the executable (KP500-Utils-EN.exe[enter])

3) choose option J - Flash with assistant (file .cab)--after opening the application I get the err msg, Error during the loading DLL. What does this mean? Im sure it has something to do with the directory, to the answer to the first question will likely solve, yes?

That might be a folder problem, make sure you current wordking directory is set to the one you placed all the files in.

You might have a corrupted or incomplete download of the V9 cab file. I added a step (e) where you can check the cab file's checksum to make sure it matches what is expected.

 

[tcol41]

Did you remember to install the V8->V9 update.zip (step 4). It is expected to fail, but you need to run it for the side-effect of getting /system mounted.

If you forget that step, the /system partition won't be mounted and adb shell will complain it can't find /system/bin/sh

Yes I downloaded it to my phone then I moved it to the root of my sd card. Is that the correct way?

That is fine, as long as you rename it to be update.zip and run it from the Recovery partition (just the first time before you run adb). That will mount /system from that on until you reboot, at which point, you'd have to re-run update.zip to get /system mounted again.

Mine looks just like this but I did do step 4 and the very first couple times that I tried this it worked (the adb shell).

I don't understand what you mean when you said that I have to re-run update.zip?

On the android recovery utility it says apply sdcard:updatezip.

When you first boot into the Recovery partition, /system will not be mounted and "adb shell" will not work. It will be looking for /system/bin/sh, which it will not find because /system is not mounted. Once you tell the Recovery to run the V8->V9 update.zip, you'll see some error message and as a side-effect, /system will be mounted and "adb shell" will work. /system will stay mounted as long as you don't reboot.

Now, if you at some point reboot the phone into Recovery, /system will once again not be mounted, and you will need to re-run update.zip to get "adb shell" working again.

Ok I just ran rageinthecage and my phone isn't restarting is it supposed to? The cmd says adb connection will be reset. restart adb server on desktop and relogin.
c:\android-sdk-windows\tools>adb

What do I do next?

So I typed in adb shell and got the #sign to appear, but I don't know if it's gonna work because my phone didn't restart after running rageinthecage.

 

[drewwalton19216801]

You need to adb shell again and continue with the instructions. The device is not supposed to reboot.

Really, I think it worked! How do I know if it worked? Everything went smoothly. I just rebooted my phone.

The phone doesn't restart. What happens is rage kills the adb server on the phone and that kicks you out of your adb shell session.

All you need to do is type "adb shell" again (which it seems you've done) and if you see the "#" in the prompt (which it seems you have), then you are rooted and can perform the rest of the steps.
